Application filed July 7, 1909. sei-inno. 506,292.

To all whom it may concern:

Be it known that I, EDWARD PossoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements 'in Ventilatore, of which the following is a specification.

The object of my invention is to provide akventilator for refrigerator 'cars or the li e.

A particular object of my efforts has been to devise an appliance which can be used in conjunction with the` hatch and plug commonly employed in car roofs. These hatches are used for the convenient replenishing of the car with ice. As now commonly employed, these hatches are closed by a closely fitting and packed member called a plug which tits snugly Within. the

beveled Walls of thehatch. Above the plug' is commonly found a cover resting upon the framing of the hatch. At present -it is necessary to raise both the cover and the plug when it is desired to ventilate the car through these hatches. When thus open, there is no protection against the entrance of rain, cinders, &c. to the interior of the car.

The principal vobject of my invention, therefore, is to provide means for permitting the hatch to be opened Without giving access thereto to rain, cinders, &c.

A further object is to so construct the ydevice that the hatch can be opened for Ventilating purposes or closed again with the minimum of labor on the part of the trainmen.

A- further object is to so construct the device that both the plug, and the ventilating appliance which I add, may be moved .to a position leaving the hatch widely open,

for the charging ofv the'car with icc with the minimum of labor. It has also been my aim to make the device posltive 1n its action so that the movement of the car` will notY jar the hatch closed when it is desired to keep it open for Ventilating purposes, or to jar it from a closed position. For this purpose, I provide a handlel for operating lsaid hatch which willbe so attached that .the'weight of said handle will act in a Inanner to hold said plug in either of said positions.

Yframe 1 1.

the following specification and claims, taken in connection with the accompanying drawings, in Which- Figure l is a. perspective View of my invention showing it's exterior appearance as applied to a car. F ig. 2 is a sectional view taken approximately through the center. Fig. 3 is a view partly in section and partly in elevation looking in the direction of the air intake. Fig. 4 is a plan view partly in section.

In the drawings, the hatch frame 11- is' pads 13 and plates 13a, the springs 14 act to press said band 15 outwardly against the hatch frame'll. The angle bar 16 is placed around the. protruding edges of the hatch frame and is fixed to the roof l0. One leg of the angle bar 16 is placed in a vertical position adjacent the hatch fran'le and carries at its upper edge a smaller angle bar 1Ga fitted over the outer edge of said hatch One leg of said smaller angle bar 1G projects inwardly over said hatch frame 11 and serves to reinforce or protect its edge. I It also serves to provide a bearingsurface u'pon which the ventilator or cover described later Inay find a support.

The casing or cover 19 is adapted to protect the hatch against the entrance of rain, cinders, &c. and is pivoted or hinged at one edge to pins 2O carried by brackets o1' lugs 22 fixed to the angle bar 16. The hinge members 2l are riveted to the sloping top 19D of said casing or cover body 19 and engage the pins 20. The verticall side walls` 1l)a are fixed to the top sheet 19b and are provided with an angle bar 18 on their inner faces, one leg of said angle bar being horizontally disposed and adapted to bear upon the angle bar 16 previously described. lhe two vertical walls 19 are connected near their bot-tom edges by another part of the said angle bar 1S. The said angle bar is given tworight angular bends as seen best in Fig. 4. A small angle bar 18l is lixed to the sheet 19 nein' the hinge 2O :ind hns :i leg standing in :in ineliiied position :ind resting :igiiiiist the :ingle hin' ltl'f.

This position is opposite to the hinged edge of the plug.

'l`lie elose iipproiieh to :i right :iiiguliii' position iilso gives them :i viiliuihle loi'kiiig eiieet in holding the plug elosed. .\,t'iiitlier iidviintiige inthe iiriiingenientl ol' the lnindle fit) in its reliiti'oii to the i'i'iinks consists in the hiet tlnity the, weight oli the hiiindle tends to hold the plug closed. lt is lixed upon the eriink iron 51 in such reliitioii that il; does not, inove downwardly l'iii' enough to `i'es'tfiipoii thev roof when the plug is elosed. To open the lniteh hy reis ing the plug 1'. the lnindle 50 is lifted by the opei'iiior iind swung to the other Side ot the raising lt) to :i position nein' to the hingesl of siiid iiising. The notion ot' the lnindle in opening und holding the plug open is vei'lv siinliir to thiit tiiking pliiee when elosiiig it :ind holding' it elosed.

'l'he iiiovenieiit. i-.oiitiiiues until' the upwiii'd inoveiiieut of the plug is the friction of the crank pin 51a against the slide bar 52, and the Weight of the handle -50 would have to be overcome before the plug could close. A

To open the hatch for the purposeof replenishing the car with ice it is only necessary to break the seal 32 and remove the pin 3l when both t-he casing 19 and the plug.

12 may be swung together about the hinged edge of thecasing. The relative positionsl of the hinges of the casing and of the plug are very eit'ective` for permitting this combined movement, while at the same time permitting an independent movement ot the plug within the casing.

I claim:
